Hello: I would like to configure sendmail such that it rejects emails
if the recipient's address was anything but for few domains. I need to
enable relaying so that internal clients can use that server to send
emails, but I do not want to send those emails if there were for the
outside domains. I started reading check_rcpt but wasn't sure if that
was the right. Any pointers are much appreciated.

Thanks

The easier way is by using access db, which has to be enabled as a
feature (it it's not already enabled). The best description on how to
use access db is in the README file under directory cf in the source,
in the section entitled "Anti spam configuration control".

I haven't tried what you want to do but (if the example in the
documentation is valid notation -- I've never used the TLD) something
like this may do the job:

To:my.domain RELAY
To:TLD REJECT

It would be even better if instead of the REJECT you define an error
message so that your users know why they can't send messages to the
outside, something like:

To:TLD ERROR:"550 Outbound mail not allowed."
